I have a 1-speed, 1-zone gas Forced-Hot_air furnace, with non-integrated humidifier on the side of it. (New England)

Two low-voltage wires go to the thermostat. Two more low-voltage wires go to the humidistat next to the thermostat.

Thermostat and humidistat are old mechanical models. I'd like to replace with one electronic one. The only one I can find is a White Rodges 1F97-391 costing ~$150. Couldn't find anything on Honeywell's site. Can anyone recommend a reliable, accurate electronic thermostat/humidistat?

The White-Rodgers is a great stat. There's a new one called Climatouch (aka Totaltouch from Carrier & Bryant dealers) that is easy to use. The illustration below doesn't show the humidity reading nor setpoint. I am trying one on my 3 stage system and so far so good. http://www.totaltouch.info

ive used that totaline touch pad thermostat, you can use it for heat pump, electric , gas. upto 2 stage a/c or 3 stage ht. as far as a thermostat for humidity control i know carrier thermidistat is excellant.
you are not going to get a thermostat / humiditstat for 50 dollars though.

The totaline that supports a humidifier also supports 3 heat and 2 cooling systems - seems like overkill - and I'm guessing it's a lot of $$ (can't even find a price on line) - is it really better than the white-rodgers?

There is a single stage Climatouch/Totaltouch. Not sure if it has the humidity control though. W-R stats are extremely reliable. The first Climatouch I tried was bad, this one is working OK. These are cheaper than the 1F95. Not sure if you'd find on the net or have to buy through a local dealer.

Thanks - it appears that the only Totaltouch with a humidistat on their website is the P206-1400 that also supports 3 heating and 2 cooling systems, dehumidification, and other stuff. It looks like it might be hard to use since we're taking advantage of so little of what it offers (Also, I suspect it might be wicked expensive, being their top-of-the-line model).

The W-R has some nice features the totaltouch lacks, like running the humidifier a bit less when there are a lot of long heating cycles (to reduce condensation on windows). It seems like a good option, and I guess I won't get anything with both for $50 - but
